02_check_open_nodeports.yml - Usage Guide

Read-Only k3s kubeadm

Purpose

This playbook finds every Kubernetes service of type NodePort that is exposed externally. It then uses the server IP from inventory (inventory_hostname) to build clickable/copyable HTTP links (for example http://192.168.1.10:31234) and prints them.

Requirements

  • kubectl must be installed and configured on the target host (master or singlenode).
  • Your Ansible inventory must define a [master] or [singlenode] group.

The playbook now runs a kubectl cluster-info access check before querying NodePorts. If kubectl is unavailable, a clear warning is printed and the NodePort query is skipped.

How to run 

# Run for customer A
ansible-playbook -i inventories/musteri_a/hosts.ini playbooks/02_check_open_nodeports.yml

# Run for customer B
ansible-playbook -i inventories/musteri_b/hosts.ini playbooks/02_check_open_nodeports.yml

Sample output

When the ping connectivity test succeeds, active NodePorts are listed and links are generated:

TASK [Ping connectivity test] **************************************************
ok: [192.168.1.10]

TASK [Kubeconfig / kubectl access check] ***************************************
